Title: Improvements in or relating to the fitting of heel seats of shoes for the reception of heels
IPC: A43D8/48
Filed: 1936-09-24
Abstract: 482,287. Heel-seat shaping-machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., and HAZELTON, G. Sept. 24, 1936, Nos. 25912 /36 and 4698 /37. [Class 17 (i)] Relates to machines of the kind described in Specifications 421,882 and 430,758 in which a heel seat fitting operation is performed on the end of a sole attached to a shoe, and consists in the provision of a masked knife for severing any stitches which may prevent the shoe being positioned in a machine of this type. The mask and knife are spring connected, so that only when the passage of the mask is obstructed does the edge of knife project beyond the mask. The device may be used when cemented soles are being operated on. As applied to the machine described in the earlier Specification, the head of the machine is provided with a bracket 60 vertically adjustable and having at its ends downwardly extending arms 62, 64. The ends of these arms carry pins 78 on which a frame 58 is pivoted. The frame is recessed to clear the heel end of a shoe, and, on either side of the recess, is formed with a slide-way for a knife and mask plate. The mask plate 77 is formed with a guide-way for the knife 54 and carries a pin 83 engaging a slot in the knife, a spring 102 connecting the mask plate with a lever 92 carrying a pin engaging a slot 101 in the knife. The plate is, thus, urged inwardly by the spring, but can yield, if it contacts with an obstruction, to expose the edge of the knife. Each of the levers 92 is provided with an operating ball .106 engaged by the end of a lever 120 pivoted at 124 to the bracket 60, the upper ends of the two levers being actuated by toggle links 130 linked to a lever 136 actuated by a treadle. A latch retains the lever 136 in operative position, which latch is automatically released by connections with the handle described in the prior Specification as actuating the trimming knife, as this handle returns to its normal position. In case the shoe should tend to be shifted by a greater resistance to the passage of the masking plate and knife on one side than the other, a serrated presser member 182 is linked to a hand lever 176. The counter gauge is connected, in known manner, to heel measuring mechanism, and is slotted to engage supporting pin. The gauge is slidably carried by the plate 58, and thus forms the rear support for this plate. In a modification, only one knife 202, Fig. 10, and masking plate 204 are provided, connected by springs 212 and entering between the shoe and sole as the shoe is pushed rearwardly up to the counter gauge in positioning the work. The first Provisional Specification refers also to Specification 306,192, [Class 17 (i)].

Title: Improvements in or relating to Apparatus for Detecting Improperly Sealed Containers
Inventor: O'NEILL THOMAS FRANCIS
IPC: G01M3/40
Filed: 1967-06-07
Abstract: 1,176,368. Proximity detector systems. BRON ELECTRONICS Inc. June 7, 1967, No.26277/67. Heading G1N. A system for rejecting faulty vacuum sealed jars by checking the concavity of the lid as they are conveyed under an inductive (or capacitative) probe of a proximity switch, also has a side proximity detector to check for jars that do not pass centrally under the top detector. The two signals are combined in a NOR-gate to control an air blast which rejects faulty jars from the conveyer. As illustrated Fig. 1 (not shown) the top probe (34) is held in a plastic skid with rounded corners, so that it rides up and sits on the lid, and the side probe is held in a plastic member (40) at lid level. Circuit Operation. As described the probes 46, 76 are inductive and connected with oscillator/detector circuits to operate trigger circuits 66, 98. The potentiometer 94 in the top (center) probe circuit is set so that the trigger circuit 98 just releases when the lid is held down by the correct vacuum to produce a "W"-shaped signal 104 at the inverter output; (in the absence of a vacuum there is no center release pulse and the output signal is of the form shown at 106). The potentiometer 62 in the side-probe circuit is set so that the trigger just operates as the edge of the lid comes closest to the probe with a jar correctly positioned. The trigger output is differentiated by capacitor 68 to produce a short pulse 72 at the inverter output. With a correctly positioned sealed jar the two pulses 72, 104 arrive simultaneously to block the NOR-gate and the rejector air-valve is not operated.

Abstract: 156,360. Chapman, W. A. Oct. 28, 1919. Jacks.-Relates to jacks of the kind in which the movable member is retained in any position on the standard by friction grip mechanism. The lifting-pillar A carries a gripper C formed with cross-bars 11, 12, between which the standard B passes, and maintained in inclined position by a spring 25. The pillar A is raised by a lever 15 which has its fulcrum in a bracket 18 formed on a member D provided with a gripper E similar to the gripper C. The fulcrum may be a block slidably mounted in guides on the top of the member D. The pillar A or member D can be adjusted on the standard by raising the short. arm of the appropriate gripper by means of the lever 15. The grippers can be released simultaneously by providing an inverted-U bolt 31 on the gripper E of such length that the lever 15 can just be inserted below its top into the socket 14 in the gripper C. The pillar A and member D may be connected by springs to avoid the necessity of separately raising the member D after each stroke of the lever. The lower gripper can also be released by pressure of the lower side of the lever 15 on a set screw 46. A similar setscrew may project from the lower side of the gripper C. In a modification, Fig. 8, the lower member D has a screw 41 engaging a sleeve 42 which bears against the pillar A and is turned by a spanner to raise the load. An auxiliary crutch 30, Fig. 1<a>, may be slidably mounted on a rod 47 carried 'by bars 48, 49 which project from the.pillar A.

Title: Improvements relating to the continuous forming of plastic materials
Inventor: TERRY ARTHUR JOHN
IPC: B29C43/22
Filed: 1966-06-14
Abstract: 1,122,089. Moulding plastic materials. BRITISH-AMERICAN TOBACCO CO. Ltd. 13 June, 1967 [14 June, 1966], No. 26407/66. Heading B5A. In a method for the continuous forming of a rod or strip of a plastic material, a wrapping strip e.g. of paper, is shaped to trough form, and plastic material in powder form is fed into the trough and heated to produce a viscous mass, the strip is then folded to enclose the material, and the deformable rod so produced is passed through plates and/or rollers to give the desired rod configuration. A band of paper is fed between upper and lower rollers and cut longitudinally into three strips 5, each provided with two lines of perforations 6, Fig. 3a. The strips are then fed between an upper roller and lower block and shaped into troughs 14, Fig. 3b, which pass below a vibrated hopper which fills them with powdered polyethylene, Fig. 3c. The fitted troughs pass to heating plates and then to a pair of forming plates, the upper one of which is triangularly grooved to produce rods 25, Fig. 3f, which are cooled and set. A pair of forming rollers may be used instead of, or in addition to, the forming plates. The rods may then be drawn through an adhesive bath, dried and reeled for storage; alternatively the wrapping strip may be removed after the final forming operation, and the rods cut to length.

Title: Improvements in or relating to omni-directional radio beacons
Inventor: PARKER BERNARD DOLLMAN
IPC: G01S1/02
Filed: 1968-07-04
Abstract: 1278263 Radio beacon identification DECCA Ltd 1 Oct 1969 [4 July 1968] 26569/68 Heading G4H To enable an aircraft to identify a navigational beacon, the beacon transmits, simultaneously with navigational information, a v.f. identification signal. In the arrangement described a 3-character identification signal is transmitted as a train of 3 groups of 6 binary bits using four voice frequencies. Two of the frequencies are used for the 0 and 1 binary states of the odd numbered of the 18 binary bits and the other two frequencies for the 0 and 1 states of the even numbered bits. The transmission of v.f. pulses from alternate pairs of voice frequencies can provide a check on the validity of the received signal. In the V.O.R. beacon transmitter shown in Fig. 1 a clock 20 triggers the first of three pulse generators 21, 29, 37, each of which delivers sequentially a single pulse on each of their six outputs, generators 29 and 37 being triggered after a short delay by the last pulse of the preceeding generator. The 3-character identification code is set into a plug-in connection unit 49 by means of permanent ties or switches, such as 55, 56, which selectively connect the pulse generator outputs to oscillators 45 to 48. Odd numbered outputs are connected to oscillators 45 or 47 and even numbered outputs to oscillators 46 or 48. The train of 18 v.f. pulses after amplification pass to the beacon V.O.R. transmitter. In the aircraft receiver (Fig. 2, not shown) the v.f. pulses of the identification signal are separated by filters and received by a binary staticizer. After decoding, the identification signal is displayed visually, either the three characters sequentially or simultaneously, or passed to a computer controlled navigational system of the kind described in Specification 1,109,402. An extra bit may be transmitted with the identification to indicate the state of the V.O.R.

Title: Improvements in or relating to well logging
IPC: G01V3/32
Filed: 1959-08-05
Abstract: 931,725. Gyromagnetic resonance apparatus. CALIFORNIA RESEARCH CORPORATION. Aug. 5, 1959, No. 26759/59. Class 37. A method of logging an earth formation from within a well bore pentrating said earth formation for the presence of hydrogenous fluids comprises: (a) establishing a first polarisation field in said earth formation to polarise protons present in the fluids in the formation; (b) interrupting the polarising field rapidly to initiate precession of the polarised protons ; (c) detecting resulting precessional signals; (d) determining from the precessional signals the rate of relaxation of the protons; (e) repeating steps (a)-(d) with a different intensity polarising field; and (f) comparing the relaxation rates. Coil 33, Fig. 1, which has elongated turns, is used both for polarising the protons and receiving the precession signal, the switches shown being electrically operated relays controlled by timing circuits. The current in coil 33 to give the polarising field Hp, Fig. 2a, is set by resistor 4, and the time of its application Tp, is determined by switch 9. The resulting polarisation is shown by the dotted curve P(Tp) the voltage of source 1 and 3 being sufficiently large to produce the sudden changes demanded, and resistors 4, 19 providing current limitation. A thyrite resistor 23 limits the voltages developed across the coil 33 by rapidly changing currents. A condenser 43 which tunes the coil circuit to the frequency of precession during reception is disconnected from the coil by switch 41 for a few milliseconds after the time t = 0, a damping resistor 39 being connected at this time to absorb much of the energy left in the coil. The signals are applied to a C.R.T. after amplification in amplifier 47 and may be photographed to provide a permanent record. The manner of analysis of the results is discussed, and the effects of temperature, viscosity, presence of magnetic material, porosity of the sub soil is described. The suppression of nuclear resonance signals from the drilling mud by the inclusion of powdered magnetite is also referred to. The apparatus can be used to determine wettability properties, information on fluid components, viscosity, and the permeability of the formation. Dimensions and component values are exemplified.
